(16)/(x)=1=(15)/(x+1)

The coefficient of x^(3) in the infinite series expansion of (2)/((1-x)(2-x)), for |x|<1 is (A)-(1)/(16)(B)(15)/(8)(C)-(1)/(8)(D)(15)/(16)

The coefficient of x^(10) in the expansion of (1+x)^(15)+(1+x)^(16)+(1+x)^(17)+… +(1+x)^(30)

The coefficient of x^(10) in the expansion of (1+x)^(15)+(1+x)^(16)+(1+x)^(17)+… +(1+x)^(30)

Solve (2^(x)+2^(-x))/(2^(x)-2^(-x))=(16^(1/x)+16^(-1/x))/(16^(1/x)-16^(-1/x))

Determine the following limit: (lim)_(x->1. 5^(\ ))f(x)= (x + 1.5)(x-1.5)

The sum of the last eight coefficiennts in the expansion of (1+x)^(15) is (1) 2^(16) (2) 2^(15) (3) 2^(14) (4) 2^(8)

Lim_(x rarr1)(x^(15)-1)/(x^(10)-1)

Evaluate : lim _(x to 1) (x^(15)-1)/(x^(10)-1)
